ABSTRACT
An instrumental system for the continuous measuring of sorption properties in porous materials is described. This system constitutes a qualitative and quantitative improvement over the referenced methodologies applicable to this type of measurement. In this work, the function of the main components of the system is described, placing special emphasis on the electronics used for controlling the transducer and actuator devices. The system has been fully computerized with specific software whereby variables such as the weight, the temperature, the relative humidity, the aqueous levels, etc. can be continuously controlled. Finally, a set of representative experiments undertaken with this instrumentation is presented, highlighting the main experimental characteristics.
